Guía

Everything about the skeletal side of assets: the skeleton itself (bone tree, virtual bones, skeleton sockets, animation slot groups, curve metadata, blend profiles, per-bone translation retargeting, notify names, compatible skeletons), the deeper parts of a skeletal mesh (LOD info, reduction and build settings, sections, morph targets, skin weight profiles, reference pose, bounds, Niagara sampling, ray tracing, mesh merge, FBX export, import settings), physics assets (bodies, shapes, constraints, profiles, collision pairs) and clothing.

Works on UE 4.27 through 5.8 (~150 tools on 5.8, ~145 on 4.27). The 5.x-only tools are the compatible-skeleton list, the skin weight profile removal and the default mesh deformer; they are hidden from tools/list on 4.27 and refused with E_NOT_SUPPORTED if called anyway. The skel.cloth_* tools require the ChaosCloth plugin and disappear when it is not enabled.

The kit is split over five classes that all expose the skel. namespace:

Class	Prefix	What
`UUeaKit_Skeleton`	`skel.`	bone tree queries, virtual bones, skeleton sockets, slot groups, curve metadata, blend profiles, retargeting modes, notify names, preview mesh, compatible skeletons, bone-tree merge/recreate
`UUeaKit_SkelMesh`	`skel.`	LOD info / reduction / build settings, sections, material slots, morph targets, skin weight profiles, reference pose, bounds, sampling, ray tracing, merge, export, import settings
`UUeaKit_SkelPhysics`	`skel.pa_`	bodies and shapes, constraints with limits and motors, constraint and physical-animation profiles, collision pairs, mirroring, auto-generation
`UUeaKit_SkelCloth`	`skel.cloth_`	clothing assets: create from a section, bind/unbind, configs, weight maps
`UUeaKit_SkelBatch`	`skel.`	folder-wide audits and bulk edits

This kit does not replace the basic mesh.sk_* tools (info, LOD screen size, materials, mesh-local sockets, bone list, morph target names, physics asset assignment). Those stay in the mesh kit; skel.* goes deeper and never duplicates a mesh.sk_* name.

Not here: animation assets (anim kit), placing skeletal meshes in a level (actor kit), skeletal mesh component settings (component kit), importing a new mesh from FBX (asset kit).

Start here

skel.get_skeleton {"skeleton":"/Game/Characters/SK_Hero_Skeleton"} — bone count, root, virtual bones, sockets, slot groups, curves, blend profiles, preview mesh, compatible skeletons, notify names, retarget sources.
skel.get_mesh {"mesh":"/Game/Characters/SK_Hero"} — LOD infos, sections per LOD, material slots, morph targets, skin weight profiles, cloth, physics assets, bounds, sampling, ray tracing and the source files.
skel.pa_get {"physicsAsset":"/Game/Characters/PA_Hero"} — bodies with their shapes and physics settings, constraints with limits and drives, profiles, disabled collision pairs, solver settings.
skel.audit_meshes {"folder":"/Game/Characters","requireLods":true,"requirePhysicsAsset":true} — the whole folder in one table.

Everything that changes an asset is transactional (edit.undo works) but nothing is written to disk until you call skel.save_mesh, skel.save_skeleton, skel.pa_save or asset.save_all.

No skeletal mesh of your own to try this on? skel.create_test_mesh {"folder":"/Game/Tmp", "name":"SK_Test"} duplicates the engine's SkeletalCube (bones Bone01, Bone02) and its skeleton into your folder; that is exactly what the self-test uses.

Recipes

Ragdoll from scratch

skel.pa_create        {"mesh":"/Game/Characters/SK_Hero","folder":"/Game/Characters",
                       "name":"PA_Hero","geomType":"sphyl","minBoneSize":8,"createConstraints":true}
skel.pa_list_bodies   {"physicsAsset":"/Game/Characters/PA_Hero"}
skel.pa_set_body_physics {"physicsAsset":"/Game/Characters/PA_Hero","bone":"pelvis",
                          "physicsType":"simulated","massScale":1.0}
skel.pa_set_constraint_limits {"physicsAsset":"/Game/Characters/PA_Hero","name":"spine_02",
                               "swing1Motion":"limited","swing1Limit":25,
                               "swing2Motion":"limited","swing2Limit":25,
                               "twistMotion":"limited","twistLimit":10}
skel.pa_disable_collision_below {"physicsAsset":"/Game/Characters/PA_Hero","bone":"spine_01"}
skel.pa_validate      {"physicsAsset":"/Game/Characters/PA_Hero"}

skel.pa_create needs the mesh to have skin weights on the bones you want bodies on; bones shorter than minBoneSize are skipped unless bodyForAll is true. Start with sphyl (capsules) — the convex types are much slower and only pay off for hands and props.

For a driven ragdoll, add a physical animation profile:

skel.pa_add_profile {"physicsAsset":"...","name":"Hit","kind":"physicalAnimation"}
skel.pa_set_physical_animation_profile {"physicsAsset":"...","profile":"Hit","bone":"spine_02",
                                        "orientationStrength":2000,"angularVelocityStrength":100,
                                        "isLocalSimulation":true}

Mirroring a half-built physics asset

Build the left side only, then:

skel.pa_mirror {"physicsAsset":"/Game/Characters/PA_Hero","fromSuffix":"_l","toSuffix":"_r"}

Every body whose bone ends with _l is copied onto the matching _r bone with its shapes mirrored across the YZ plane (X negated, yaw and roll flipped). Use skel.pa_copy_body for a single bone.

Retarget-ready skeleton

skel.apply_retarget_preset {"skeleton":"/Game/Characters/SK_Hero_Skeleton","preset":"humanoid"}
skel.add_virtual_bone      {"skeleton":"...","source":"hand_l","target":"foot_l"}
skel.add_compatible_skeleton {"skeleton":"...","other":"/Game/Mannequin/UE4_Mannequin_Skeleton"}

The humanoid preset puts the root and every IK/virtual bone on Animation, the pelvis on AnimationScaled and everything else on Skeleton, which is what a proportion-independent retarget needs. Pass pelvisBone when the pelvis is not called pelvis/hips/spine_01. skel.add_compatible_skeleton is UE 5 only and lets an animation authored on the other skeleton play directly on this one.

LOD chain and section cleanup

skel.generate_lods   {"mesh":"/Game/Characters/SK_Hero","count":4,
                      "percents":[0.5,0.25,0.1],"screenSizes":[0.5,0.25,0.1]}
skel.set_lod_info    {"mesh":"...","lod":3,"bonesToRemove":["index_03_l","index_03_r"],
                      "rebuild":true}
skel.list_sections   {"mesh":"...","lod":0}
skel.set_section     {"mesh":"...","lod":0,"section":2,"generateUpToLod":1}

skel.generate_lods needs a mesh reduction plugin (SkeletalReduction ships with the engine but has to be enabled); it fails with E_INTERNAL otherwise. generateUpToLod on a section makes that section disappear past the given LOD — the cheapest way to drop buckles and buttons at distance. skel.set_lod_reduction and skel.set_lod_build_settings tune the same LOD without rebuilding unless you pass rebuild: true.

Morph target management

skel.list_morph_targets  {"mesh":"/Game/Characters/SK_Hero"}
skel.rename_morph_target {"mesh":"...","name":"blendShape1","newName":"JawOpen"}
skel.copy_morph_targets  {"mesh":"/Game/Characters/SK_HeroLod","from":"/Game/Characters/SK_Hero"}
skel.remove_all_morph_targets {"mesh":"/Game/Characters/SK_HeroProxy"}

copy_morph_targets refuses meshes whose LOD 0 vertex counts differ: morph deltas are indexed by vertex, so the topology must match exactly.

Mesh merge for modular characters

skel.merge_meshes {"meshes":["/Game/Mod/SK_Torso","/Game/Mod/SK_Legs","/Game/Mod/SK_Head"],
                   "folder":"/Game/Mod","name":"SK_Merged","stripTopLods":0}

Every source must be bound to a compatible skeleton; the merged asset gets the first source's skeleton unless you pass skeleton. Merging is an editor-time bake — for runtime swapping use leader-pose components from the component kit instead.

Cloth

skel.cloth_create_from_section {"mesh":"...","lod":0,"section":3,"name":"Cloak",
                                "removeSection":false,"physicsAsset":"/Game/Characters/PA_Hero"}
skel.cloth_set_config {"mesh":"...","name":"Cloak",
                       "values":[{"key":"BendingStiffness","value":"0.7"}]}
skel.cloth_set_weight_map_value {"mesh":"...","name":"Cloak","lod":0,"map":0,"value":10.0}

skel.cloth_set_config writes by reflection, so it works with any simulator config the enabled cloth plugin exposes; call skel.cloth_get_config first to see the property names. Weight map target 0 is MaxDistance, 1 BackstopDistance, 2 BackstopRadius.

Folder-wide work

skel.audit_skeletons        {"folder":"/Game/Characters"}
skel.batch_set_physics_asset {"folder":"/Game/Crowd","physicsAsset":"/Game/Crowd/PA_Shared",
                              "onlyMissing":true}
skel.batch_retarget_modes   {"folder":"/Game/Characters","preset":"humanoid"}

skel.audit_skeletons scans the registry once and reports how many meshes and animations use each skeleton, so orphaned skeletons stand out immediately.

Gotchas

4.27 vs 5.x accessors. The kit hides every difference behind its own shim, but the tools that simply do not exist below UE 5 are hidden from tools/list: skel.list_compatible_skeletons, skel.add_compatible_skeleton, skel.remove_compatible_skeleton, skel.remove_skin_weight_profile (5.0+) and skel.set_default_mesh_deformer (5.1+).
Reduction needs a plugin. skel.generate_lods, skel.regenerate_lod, skel.remove_lod and skel.batch_regenerate_lods all go through the engine's skeletal reduction path. Without a mesh reduction plugin they fail instead of silently doing nothing.
Rebuild costs. set_lod_info, set_lod_reduction, set_lod_build_settings and set_ref_pose_bone take rebuild; leave it false while you make several changes, then call skel.rebuild_mesh once. Rebuilding a character mesh takes seconds, not milliseconds.
Reference pose edits are dangerous. skel.set_ref_pose_bone changes the bind pose, which breaks existing animations and invalidates the physics asset. Regenerate the physics asset with skel.pa_regenerate afterwards, and use skel.reset_ref_pose to go back to the skeleton's pose.
Virtual bone names. The engine names virtual bones VB <source>_<target>. add_virtual_bone returns the actual name in createdName; rename_virtual_bone and remove_virtual_bones accept the name with or without the VB prefix (it is added for you).
Curve metadata moved. UE 5.7 removed smart names; the kit uses the new FCurveMetaData API there and the smart-name container below it. The tool shapes are identical, but skel.rename_curve fails on a name that is already taken on both paths.
Cloth plugin. Every skel.cloth_* tool declares RequiresPlugin="ChaosCloth". The plugin is off by default; enable it in the project before the tools become callable. The kit never links against the plugin, so its module rename between 4.27 (Chaos) and 5.x (ChaosCloth) does not matter.
Material slot removal. skel.remove_material_slot refuses a slot a section still uses; point the sections elsewhere with skel.set_section first. Removing a slot shifts every higher section material index down by one, which the tool does for you.
Physics asset deletion. skel.pa_delete fails while a mesh still references the asset; clear it with skel.set_physics_assets {"mesh":"...","physicsAsset":""} first.
